The present invention relates to a digital reader for urination analysis. In particular, the present invention relates to a digital reader for urination analysis capable of preventing contamination of the reader by a test article.

In general, the urination assay strip chip has a variety of individual test items. Specifically, there are items such as occult blood, bilirubin, urobiliogen, ketone bodies, proteins, nitrites, glucose, pH, specific gravity, white blood cells, vitamin C, and the like.

Urine test by the test strip method is a semiquantitative test (semiquantitative test) to screen the various diseases of the body first, and is a method to check the abnormality of the body early. This is very useful because it is easy to collect urine, does not burden the examinee with the test, and the result can be determined immediately. The urination analysis strip chip displays the results so that the examinee can visually confirm the abnormality of the above mentioned items. However, such strip chips may have a color gamut that is difficult to visually determine the color change resulting from the detection due to the characteristics of the test part for each test item attached to the plastic film. There is a disadvantage that the accuracy may be reduced, such as different discrimination.

In addition, the display unit 220 for displaying a test result may be included.

The light source unit 230 is configured by combining three color light emitting diodes (LEDs), that is, red, blue, and green light emitting diodes (LEDs).

The three color light source elements of the light source unit 230 can be controlled discontinuously in a switching form. For example, the red diode is operated for a certain time, and the signal value R of the photodiode in response is temporarily stored. The green diode is operated for the next predetermined time, and the signal value G of the photodiode in response is temporarily stored. Finally, the blue diode is operated for a predetermined time, and the signal value B of the photodiode in response is temporarily stored. Using the stored values of R, G, and B, the concentration of the target sample may be measured by the Hue value, and the mounting of the chip and the abnormality of the device may be confirmed by the Intensity value.

The light receiver 240 may use a silicon sensor such as a silicon photo diode or a photo triode. By configuring the sensors in an array, it is possible to ensure sensitivity and ease of mounting the biochip.

The operation of the reader according to the present invention having such a structure will be described.

When the biochip 215 is inserted into the reader, the switch is turned on, and the biochip 215 insertion signal is applied to the micro control unit 180. When the biochip 215 insertion signal is applied, the micro control unit 180 determines that the biochip 215 has been inserted into the reader, and applies the power for driving the light source unit 230 including the three-color light emitting diodes. At this time, the micro control unit 180 applies power to the three-color light emitting diode in the form of discontinuous switching.

Then, light is output by the light source unit 230, and the output light is reflected by each inspection region of the biochip 215 through the light distribution unit 250 and received by the light receiving unit 240.

First, each time the reader is powered on, each of the three color light emitting diodes reads the received signal value of the light receiver 240 for the light source signal strength in the initial state, and performs signal correction for the light source. For calibration, a white or black calibrator, which is a separate standard, can be added inside the reader. By doing so, there is an advantage that the accuracy and reproducibility of the measurement signal can be obtained.

The light receiver 240 converts the received optical signal into an electrical signal. The electrical signal converted by the light receiving unit 240 is signal processed and analyzed by the micro control unit 180 to display the result through the display unit 220.

In addition, the micro control unit 180 records the read result on the RFID chip, or transmits to the remote terminal desired by the user through the mobile communication modem.
